##### Table of Contents

PART I

Item 1. Business.

This Annual Report on Form 10-K relates to the Series 2002-1G WST Trust (the Trust) and the
Class A Mortgage Backed Floating Rate Notes (the Class A Notes) issued pursuant to the Note Trust Deed dated as of March 14, 2002, between Westpac Securities Administration Limited, as Trustee (the Issuer Trustee);
Westpac Securitisation Management Pty Limited (the Trust Manager) as trust manager; and Citibank, N.A., London Office, as Principal Paying Agent and the Class B Mortgage Backed Floating Rate Notes (together with the Class A Notes,
the Notes). Capitalised terms used in this Form 10-K and not defined have the same meanings ascribed to such terms in the Prospectus for the above-referenced Class A Notes. The only business of the Trust is the collection and
distribution of payments on the residential mortgage loans in the manner described in the Registration Statement on Form S-3 (File No.333-32944) (the Registration Statement). Accordingly, there is no relevant information to report in
response to Item 101 of Regulation S-K.

Item 2. Properties

The Registrant and the Trust do not have any physical properties.
Accordingly, this item is not applicable.

Item 3. Legal Proceedings.

The Registrant knows of no material legal proceedings involving the Trust, the Registrant, the
Registrants subsidiaries, or the Issuer Trustee, nor any material legal proceedings involving the Registrants or Trusts property.

Item 4. Submission of Matters to a Vote of Security Holders

No votes or consents of
Noteholders were solicited during the fiscal year for any purpose.

PART II

Item 5. Market for Registrants Common Equity and Related Stockholder Matters

The Notes are not traded on any nationally
recognised exchange in the United States. The Class A Notes are listed and exchanged on the London Stock Exchange. Since the Trust pays no dividends with respect to the Notes, the information required by Item 201 of Regulation S-K
regarding dividends is inapplicable to the Trust. See Exhibit 99.1 for information with respect to distributions to Noteholders.

Item 6. Selected Financial Data.

The regular quarterly Noteholders Reports, which are required to be included with each
quarterly distribution of the Trusts assets to Noteholders, set forth for the prior quarter, all of the relevant financial information required by the Note Trust Deed to be reported to Noteholders. The Noteholders Reports for the Payment Dates
in September 2005, December 2005, March 2006 and June 2006 are consolidated herein as Exhibit No. 99.1. The foregoing presents all relevant financial information relating to the Trust. Because of the limited business activity of the
Trust, the Selected Financial Data specified in Item 301 of Regulation S-K would not provide any meaningful additional information.

Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operation

Because of the limited business
activity of the Trust, the presentation of Managements Discussion and Analysis of Financial Condition and Results of Operations, as otherwise required by Item 303 of Regulation S-K, would not be meaningful. All relevant information is
contained in the Noteholders Reports (filed under Current Reports on Form 8-K) as described above.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Currency Exchange Control Risk Interest and principal payments
to holders of Class A Notes are paid in United States dollars (U.S. dollars). However payments on the Housing Loans are received by the Issuer Trustee in Australian dollars, in Australia (the Collections). Pursuant to Certain
swap agreements (the Swap Agreements) the Issuer Trustee is required to pay a portion of the Collections to swap counter parties (the Currency Swap Providers) who in turn pay, at the direction of the Issuer Trustee, U.S.
dollars to the Paying Agent for payment on to the Noteholders (the Currency Swaps). It is possible that in the future Australia may impose exchange controls that affect the availability of Australian dollar payments for making payments
under the Currency Swap. The holders of the Class A Notes will bear the risk of the imposition of foreign exchange controls by the Australian government that impact upon the Issuer Trustees ability to exchange the Collections for U.S. dollars.
The Issuer Trustee has no control over such risk, which will generally be affected by economic and political events in Australia. If the Issuer Trustee does not pay some or all of the amount in Australian dollars which it is required to pay the
Currency Swap Providers under the Currency Swaps, the Currency Swap Providers are only required to pay the U.S. dollar equivalent of the amounts they actually receive. In such event, it is unlikely that the Trust would have sufficient U.S. dollars
to make the payments due on the Class A Notes.

Australian laws control and regulate or permit the control and regulation of a broad range of payments and
transactions involving non-residents of Australia. The Trust, pursuant to a number of exemptions, authorities and approvals, is not restricted from transferring funds from Australia or placing funds to the credit of non-residents of Australia
subject to the following limitations:

a. withholding taxes in relation to remittances or dividends (to the extent they are unfranked) and interest
payments;

b. a restriction on buying, borrowing, selling, lending or exchanging foreign currency where the transaction relates to property, securities or
funds:



|(i) | owned or controlled directly or indirectly by, or otherwise relating to payments that are greater than $100,000 by or on behalf of:
|--- | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | the Embassy of the Federal Republic of Yugoslavia;
| | - |  | --------------------------------------------------



| |  |  | the Consulate-General of the Federal Republic of Yugoslavia; and
| | - |  | ----------------------------------------------------------------



| |  |  | the National Bank of Yugoslavia;
| | - |  | --------------------------------



|(ii) | owned or controlled by, or otherwise relating to payments, directly or indirectly, to or for the benefit of:
|---- | ------------------------------------------------------------------------------------------------------------



| |  |  | certain persons including supporters of the former Milosevic regime; and
| | - |  | ------------------------------------------------------------------------



| |  |  | ministers and senior officials of the Government of Zimbabwe;
| | - |  | -------------------------------------------------------------

c.
accounts of persons identified as being associated with terrorism such as the Taliban, Osama bin Laden, a member of the Al-Qaeda organization and a person or entity named in paragraph 1(a), (b) or (c) of the United Nations Security Council
Resolution 1390 (2002) remain frozen, and transactions with these persons and entities prohibited, under Regulation 6A of the Charter of the United Nations (Terrorism and Dealings with Assets) Regulations 2002, made under the Charter of the United
Nations Act 1945;

d. a prohibition on:



|(i) | using or dealing with an asset owned or controlled directly or indirectly by a person or entity mentioned in paragraph 1(c) of the United Nations Security Council Resolution 1373
(2001) or paragraph 23(b) of the United Nations Security Council Resolution 1483 (2003), or allowing or facilitating the use of dealing with such an asset; and
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(ii) | making an asset available to a person or entity mentioned in paragraph 1(c) of the United Nations Security Council Resolution 1373 (2001) or paragraph 23(b) of the United Nations
Security Council Resolution 1483 (2003), unless otherwise authorized by the Australian government.
|---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In relation to the restrictions referred
to in paragraph (ii) above, the Reserve Bank of Australia may approve certain transactions in circumstances it deems appropriate.

Currency Exchange Risk.

Interest and principal on the Class A Notes are payable in U.S. dollars and the Trusts primary source for funding its payments on the Class A Notes
is its Collections on the Housing Loans, which will be sourced in Australian dollars. If the Currency Swap Providers were to fail to perform under the Currency Swaps or were to be discharged from such performance because of a default thereunder by
the Trust, the Trust might have to exchange its Australian dollars for U.S. dollars at an exchange rate that is less favourable to the Trust than when the Currency Swaps were entered into and might therefore not have sufficient U.S. dollars to make
timely payments on the Class A Notes, even though the delinquency and loss experience on the Housing Loans may be acceptable.

Item 8. Financial Statements and Supplementary Data

As discussed above, furnishing the financial information required by
Item 8 of Form 10-K would not add any relevant information to that provided by the foregoing statements. Because the Notes are essentially pass-through securities, the Trust will have income only in the limited sense of
collecting payments on the residential mortgage loans and receiving any net payments under the Trusts interest rate swaps. The only material items of expense for the Trust will be the amounts paid as servicing compensation and
potentially certain payments relating to any credit enhancement facilities. The Noteholders Report (filed under Current Reports on Form 8-K) provides complete information on the amounts of the income and expenses of the
Trust.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure

None.

PART III

Item 10. Directors and Executive Officers of the Registrant

Since the Trust will not have
any directors or executive officers, this item is not applicable.

Item 11. Executive Compensation

Since the Trust will not have any directors or executive
officers, this item is not applicable.

Item 12. Security Ownership of Certain Beneficial Owners and Management.

The following table sets forth (i) the name and
address of each entity owning more than 5% of the outstanding principal amount of the Class A Notes or Class B Notes; (ii) the principal amount of the Class of Notes owned by each, if known, and (iii) the percent that the principal
amount of the Class of Notes owned represents of the outstanding principal amount of the Class of Notes. The information set forth in the table is based upon information obtained by the Trust Manager from the Trustee and from The Depository Trust
Company as of June 30, 2006. The Trust Manager is not aware of any Schedules 13D or 13G filed with the Securities and Exchange Commission in respect of the Notes.
